You are Ernie the Emp (Emp as in Imp because Ian Imp or Ivan Imp sounds funny) or Gary the Goblin. So as Ernie or Gary you must eat as many humans as possible. When you eat one human go back into your hut and then come out and there will be another human there. Wait five minutes for a suprise. Move Ernie with the arrow keys, and Gary with W, A, S, D keys.
